  • no need for additional routing fittings due to flexibility
  • no special skills and extra equipments are required for installation
  • easy transportation, loading and preservation because of light weight
  • environmentally friendly and safe material
  • the polymer products plant produces new types of double polyethylene pipes. The heavy surface and light weight make them irreplaceable. These pipes ensure the safety of energy and telecommunication lines.

Double corrugated pipes are resistant to physical, chemical and technical impacts at a depth of 1-15 m and in the temperature range of -40ºС to + 90ºС. At the same time, corrugated pipes increase the life of engineering installations, resulting in minimal loss of time for their repair. Depending on the application area, three color corrugated pipes are manufactured at the STP: red – for power transmission lines, blue – for telecommunication lines, black – for other purposes. Smooth inner surface minimizes friction.

The positive aspects of double corrugated pipes produced in Polymeric Products Plant, STP can be summarized as follows:

  • Easy cabling due to the smooth inner surface during installation;
  • long term service life and economically efficiency
  • prerequisite for installation of drainage systems.


  • top layer HDPE;
  • inner layer HDPE;

Application areas:

  • Protection of low and high voltage cables from mechanical impacts:
  • Protection of environment from the aggressive impacts during cabling on the ground
  • installation with any camouflage methods (as part of the concrete)
  • discharge of non-pressure wastes, groundwater and rainwater

Operation temperature:

  • from -40 °C to +90 °C


  • Outside wall: red (electricity), blue (telecommunication), black (others)
  • inside wall: white, yellow

Double corrugated pipes made of polypropylene are designed for drainage sewage, rainwater and ground water in external water transmission systems. These universal construction pipes are widely used practically in all areas like industry, agriculture, hydrotechnical and water installations, railway and automobile roads construction.

Double corrugated non-pressure polypropylene pipes are manufactured by co-extrusion method based on German technology. The smooth inner surface and outer corrugated surface. The top layer is typically painted with black, because it protects the pipe from the impacts of ultraviolet rays. The inner part is usually painted yellow or white. The exploitation period of pipes is more than 50 years. The monitoring on quality of polypropylene pipes is fulfilled in AZS ISO/IEC 17025:2009 accredited laboratory.

STP ensures organizations performing regional and global construction of collector and drainage systems ­with high quality polymer pipes in virtue of production potential and transport infrastructure

Double corrugated pipes without pressure made of double polypropylene have following specific characteristics different from other pipes:

  • quick and easy installation due to pipe socket junction;
  • possibility of laying the pipes on the ground of open field, even passing under the roads with great dynamic loadings;
  • having large annular stiffness and resisting to massive weight (8 kN/m 2 or SN8) in spite of their small mass;
  • due to its smooth inner surface, ­non-accumulation of various additives and sediments;
  • having a capability to transport water up to +95 °C temperature.

Polypropylene PPR pipes

Today, plastic products have become an integral part of our life with technological innovations. As a result, people have already started to prefer plastic pipes that are cheaper, lighter, resistant to natural impacts and easy to use than metal pipes that they used once in their daily life.

Polypropylene PPR pipes are considered to be one of the last new products among plastic pipes. Hgh quality PPR pipes are also produced at STP's Polymeric Products Plant, that are used for the installation of hot and cold water supply systems.

Advantages of PPR pipes produced by STP:

  • Corrosion and chemical resistance: Pipes are resistant to corrosion and aggressive environments.
  • Flow velocity: Because of its smooth surface, these pipes increase the flow velocity.
  • Environmental cleanliness: Polypropylene, used as raw material, is unreactive with water, so it does not add extra taste to water; Due to its slippery inner surface, creation of bacteria, organic and inorganic sediments are not observed.



PE 100 polyethylene welding fittings are connecting components for polyethylene pipes made from PE 100 brand high density polyethylene. These fittings are produced connecting the polyethylene pipe cuttings by welding. Produced PE 100 polyethylene welding fittings have the following configurations and types: 15°, 22.5°, 30°, 45°, 60° and 90°.


Cast fittings are produced by molding method of polyethylene (PE 100) under pressure and temperature. Pipe fittings are used when changing the direction of the pipe system, distribution or conversion to another diameter. An important advantage of these fittings is the ease of manufacture and low cost. Their installation is carried out by welding, which reduces financial costs and reduces additional costs. Bends, flanges, crossovers, triples and closers made of PE 100, with a diameter of 63÷315 mm are used in water and gas lines.


PPH "Homogen polypropylene" fittings are used to connect pipes to the internal sewerage networks. Since these fittings have high physical and mechanical properties, they are resistant to aggressive environments. These properties can be attributed to both inner and outer surfaces of the fittings. Unlike PVC fittings, they are more shock-resistant.
